State courts almost always have the power to hear cases involving events that took place in the state where the court sits or if defendants reside in or are served with a summons and complaint in that state.
So unless your case involves one of the few types of cases over which federal courts have exclusive jurisdiction (copyright violations, patent infringement, or federal tax claims), the state court in the state in which you live will probably have jurisdiction to hear your case, whether you're seeking an adoption, guardianship, or divorce, suing a landlord or a tenant, have a consumer complaint against a contractor or repair shop, want to go to small claims court, need to probate a will, or are involved in one of the vast variety of other kinds of legal disputes.
Example: Dobbs, a Michigan resident, buys a used car from Rick's Used Cars, a Michigan business. A few weeks later the car breaks down, and Dobbs learns that it needs a new engine. Dobbs sues Rick's Used Cars for fraud and breach of contract in Michigan state court, which has jurisdiction because Rick's is a Michigan business.
Example: Allnut lives in Arizona and is involved in a traffic accident in Arizona with Marlowe, a Texas resident. Allnut could file a lawsuit in Arizona state court, which would have jurisdiction because the accident took place there. (Every state has a "motorist" law that confers jurisdiction on its state courts to hear cases involving all traffic accidents occurring in that state.) Allnut could also file suit in Texas, where Marlowe resides, because state courts almost always have jurisdiction to hear cases filed against defendants who live in the state. (However, Allnut could not file the lawsuit in California or Florida in an effort to combine a vacation with legal business. Neither state is the site where traffic accident-related events occurred or the defendant lives.)
Example: Elaine, a New York citizen, sues Officer Kramer (also a New York citizen) for violating her civil rights by falsely arresting her. Elaine bases the suit on a federal statute, 42 United States Code Sec. 1983, and asks for damages of $10,000. A New York federal court has the power to hear Elaine's case. Because the case is based on (arises under) a federal statute, the New York federal court has jurisdiction even though Elaine and Officer Kramer are citizens of the same state and Elaine seeks less than $75,000. Alternatively, Elaine could file the lawsuit in New York state court, which would have power to hear the case because the arrest occurred in New York and both Elaine and Officer Kramer live there. The state court has "concurrent jurisdiction" with the federal court and enforces the federal law as it would a state law. Elaine can go "forum shopping" between New York federal and state court.
Most lawsuits that can be filed in federal district court can also be filed in state court. Federal courts have exclusive jurisdiction only in a very few kinds of federal question cases, such as lawsuits involving copyright violations, patent infringement, or federal tax claims.
This means that plaintiffs in all diversity jurisdiction cases and nearly all federal question cases have a choice of suing in federal or state court. Lawyers call the process of deciding which court is best for a plaintiff's case "forum shopping."
For example, a plaintiff who has a choice of courts may consider such factors as:
Consult a legal coach for advice on forum shopping. Many subtle factors can affect forum shopping. If you have a choice of courts, it would be wise to consult with a legal coach who has experience in both federal and state courts.
